| 摘 要： | 【目的】研究肉鸡采食行为对生产性能的影响,为鸡饲养管理提供参考依据。【方法】采用由自动饲喂系统收集的45日龄黄羽肉鸡采食行为和生产性能数据,通过统计描述鸡采食行为24 h的变化规律,对鸡群的各个采食行为和生产性能进行相关性分析。【结果】鸡群1 d中存在2个采食高峰,分别是06:00—10:00和17:00—19:00;在采食高峰期前期或末期鸡群的平均单只采食速率更高,最高约为3.0 g·min~(–1);鸡只的单次采食行为(单次采食量、单次采食时长、单次采食速率)与生产性能(日均采食量、平均日增质量、饲料转化率)存在显著相关;鸡只的日均采食次数与平均日增质量存在显著负相关,与饲料转化率存在显著正相关;鸡只日均采食时长与生产性能无显著相关。【结论】鸡的单次采食行为与生产性能之间联系紧密,选育采食次数少的鸡只可提高生产性能。
